One of the japanese 3D-Gurus(Stereomaker=?) has shown its 1000D(XS-solution) on facebook. Ask openkmq-man o berlin about that. He published two images of the setup/wiring. I have seen diodes too. maybe we will see that or is already shown on photo3d-yahoo.

Yes, for cameras with simple switch for triggering you need diodes due to different potentials of 2 cameras.

I think it was stereophotomaker-guru Masuji Suto. btw: is working on a html5-3dvideo-solution-is already working(not all browsers).anaglyph and paralle shown.
